Obstetrics & gynaecologyThu, 17 Jan 2019 09:35:05 ESTnews466940095Perspectives on gene editingMedicine is at a turning point, on the cusp of major change as disruptive technologies such as gene, RNA, and cell therapies enable scientists to approach diseases in new ways. The swiftness of this change is being driven by innovations such as CRISPR gene editing, which makes it possible to correct errors in DNA with relative ease.https://medicalxpress.com/news/2019-01-perspectives-gene.html
GeneticsThu, 10 Jan 2019 07:12:51 ESTnews466326726Discovery in cell development changes understanding of how genes shape early embryosOur bodies hold roughly 14 trillion cells, each containing a nucleus with DNA measuring two meters long by 20 atoms wide. To fit inside each nucleus, DNA coils around specialized proteins. These spools of wrapped DNA inhibit gene regulatory proteins from binding to protein-coding stretches along the genome, which help keep genes in the "off" position when they're not needed.https://medicalxpress.com/news/2019-01-discovery-cell-genes-early-embryos.html
GeneticsThu, 03 Jan 2019 14:00:02 ESTnews465732637Natural selection in the womb can explain health problems in adulthoodConditions encountered in the womb—when the embryo consists of only about 100 cells—can have life-long impact on health. Scientists previously assumed that this is because embryos respond to adverse conditions by programming their gene expression. Now an international team of researchers at the Leiden University Medical Center, Wageningen University and Research, Lund University, Columbia University Mailman School of Public Health in New York propose a radically different alternative. Rather than being programmed by the environment, random differences in gene expression may provide some embryos with a survival advantage, in particular when conditions are harsh. By studying DNA methylation, an important mechanism to control gene activity, the researchers found that a specific part of the DNA methylation pattern was missing among famine-exposed individuals. The findings are published in the journal Cell Reports.https://medicalxpress.com/news/2018-12-natural-womb-health-problems-adulthood.html

Today, Columbia University Fertility Center announced it has developed and built the first weight-based scale safety system to protect stored eggs and embryos in response to these reported failures. Through its custom, web-enabled safety system, Columbia University Fertility can now continuously monitor the real-time weights of its storage tanks and can detect impending tank failures sooner. As a result, it reduces the risk of any damage to embryos and eggs by greatly increasing the time available to intervene should an issue arise. Columbia University Fertility Center is the first and only fertility center to offer this additional layer of protection in its clinic.https://medicalxpress.com/news/2018-11-custom-weight-based-safety-embryos-eggs.html
Obstetrics & gynaecologyThu, 01 Nov 2018 10:51:48 ESTnews460288303A single missing gene leads to miscarriageA single gene from the mother plays such a crucial role in the development of the placenta that its dysfunction leads to miscarriages. Researchers from the Medical Faculty of Ruhr-Universität Bochum (RUB) have observed this in so-called knockout mice that were specifically modified for this purpose. These mice lack the gene for the transcription factor Math6. By conducting further analyses, the research team is now hoping to gain new insights into the role the gene plays in recurrent miscarriage in humans. The researchers headed by Professor Beate Brand-Saberi published their results in the journal Scientific Reports on 9 October 2018.https://medicalxpress.com/news/2018-10-gene-miscarriage.html
